2. Web 3.0 vs. Web3: Center of Differences and Debate
1. The Evolution of the Web: The Development and Change of the Internet
Today's web has established itself as the most important tool through which billions of people worldwide read, write, share information, and communicate with each other. However, the interactivity and openness of the web as it exists today was not achieved in an instant. The internet has evolved through multiple stages, and throughout that process, methods of information distribution, user experiences, and technological foundations have significantly changed. The development of the web can be broadly divided into Web 1.0, Web 2.0, and currently discussed Web 3.0 and Web3, with each era possessing different characteristics.
Web 1.0: The Era of Static Information Provision
Web 1.0 was developed in 1989 by Tim Berners-Lee, the founder of the World Wide Web, and continued until 2004. Web 1.0 is often called the "read-only web," and basically served the role of providing information through static websites. Websites of this period mostly contained static content consisting of simple HTML documents, with almost no direct user participation or interaction.
Also, in Web 1.0, early online communication means such as email existed, but text-based message exchange was dominant, and the ability to upload images or multimedia files was limited. Search functions also remained at a very basic level, and users had to use online directories to find specific information.
Websites of this period were mostly personal web pages operated primarily through ISPs (Internet Service Providers) or free web hosting services. Interestingly, some websites had models where users had to pay each time they viewed information. Web 1.0 performed the role of a "Content Delivery Network (CDN)," and users were in a structure of passively consuming given information.
Web 2.0: The Era of Participation and Interaction
Web 2.0, beginning in 2004, is the main form of the internet we experience today. Also called the "read-write web," Web 2.0 created an environment where users can directly create content, share, and interact. This enabled new web services such as social media, blogs, online communities, and collaborative platforms beyond simple information provision.
The representative characteristic of this period is the explosive increase in User-Generated Content (UGC). As social media platforms like Facebook, YouTube, and Twitter appeared, users transformed from simple information consumers to content producers. Websites were no longer static HTML pages but operated based on databases and dynamic content, and as technologies like AJAX and JavaScript developed, real-time data updates and richer user experiences became possible.
Web 2.0 evolved from a simple information sharing tool to a platform connected to the digital economy. The internet combined with mobile devices and transformed into an application-centered environment, leading to the emergence of mobile-centered services like Instagram, Uber, and PayPal. Also, as "E-commerce" grew rapidly, a structure formed where platforms like Amazon dominate the market.
However, Web 2.0 has limitations in that it operated based on centralized platforms. Users use social media, online services, and cloud storage, but ownership of that data has become a form where major platform companies like Google, Facebook, and Amazon monopolize it. This led to the rise of issues such as personal information protection problems, data monopolization, and platform dependency, and Web 3.0 and Web3 emerged as new paradigms to overcome these limitations.
2. Web 3.0 vs. Web3: Center of Differences and Debate
In the process of web evolution, two concepts are frequently confused causing confusion. Web 3.0 and Web3 are fundamentally different concepts, but many people perceive or fail to distinguish them as identical. Web 3.0 is based on the "Semantic Web" and aims for efficiency and intelligence of the internet through artificial intelligence (AI) and data linkage. In contrast, Web3 is centered on "Blockchain and Decentralization," a movement to strengthen user data sovereignty and dismantle the centralized power of platforms.
Let us now examine what Web 3.0 and Web3 each mean, and analyze how these two differ.
Web 3.0: Combination of Semantic Web and AI
Web 3.0 is a concept proposed by Tim Berners-Lee, the founder of the World Wide Web (WWW), and is also called the "Semantic Web." It aims to build a smarter internet environment by enabling machines to understand and interpret web data. In Web 3.0, rather than simply providing information, AI, machine learning (ML), big data analysis, and others are utilized to process and connect data more precisely.
Tim Berners-Lee argued through Web 3.0 that the internet should become not just an information repository but an environment where machines understand human language, grasp context, and operate more efficiently. He envisioned an internet where machines and humans cooperate together, saying 'When the semantic web arrives, trade, administration, and our daily lives will be handled through conversations between machines, and intelligent agents will finally be realized.'
For example, in Web 3.0, when a user searches for specific information, rather than simple keyword matching, the search engine can analyze context and provide more accurate results. Also, even without users entering information on multiple websites, the goal is to support information entered once in a centralized data repository like "Solid Pod" to be utilized on other platforms as well.
The concept of Web 3.0 is very rational, but there are problems that make it difficult to popularize in reality. The technology for semantically processing data has not yet been implemented in complete form, and practicality was low because major platform companies have not actively adopted this technology.
Web3: The Era of Blockchain and Decentralization
Web3 is a concept proposed in 2014 by Gavin Wood, co-founder of Ethereum, meaning next-generation internet based on blockchain and decentralization. The core goal of Web3 is to return data and authority that companies monopolized in existing Web 2.0 to users.
Web3 utilizes blockchain to enable data ownership and transactions without centralized servers. For example, instead of companies like Facebook and Google collecting user data to generate revenue, in Web3 users can directly manage their own data and conduct trustworthy transactions through blockchain.
In the Web3 environment, rather than logging in with a Facebook account, users can directly manage their data through cryptocurrency wallets and set access permissions for specific services. This shows a big difference from the existing platform-centered Web 2.0 model.
Also, Web3 is forming an even more expanded digital ecosystem combining with the metaverse. The metaverse is positioning itself as a space not just as a virtual space but where users own, trade digital assets and build their identities. Blockchain-based NFTs (Non-Fungible Tokens) are used as means of proving digital asset ownership, and individuals can participate in new economic systems through their own avatars and virtual assets. Along with this, Web3 is attributing data sovereignty to users to reduce platform-centered data control, and developing semantic web technology that provides more personalized services and customized information.
Ultimately, Web3 is a new paradigm that changes the fundamental structure of the internet beyond simple technological innovation. Changes in data ownership, the emergence of a decentralized economy, personalized internet services, and the expansion of metaverse and digital assets will make future internet environments more transparent and trustworthy. To lead these changes, continuous research and innovation in blockchain, artificial intelligence, and distributed network technologies are necessary, and this will have a great impact on the digital economy and social structure going forward.
